摘要
应用电负性相等原理,提出了计算配体中各原子部分电荷和电负性的简便近似的方法,计算了54种配体。根据计算结果,应用电中性原理讨论了配位原子的条件,CO,P(Ⅲ)和As(Ⅲ)化合物的配位原子的情况,以及SCN^-等的键合异构现象。
Using the balancing principle of electronegativity an approximate calculating meth-
od for the fractional charge and electronegativity of all atoms in the ligands is proposed
and data of fifty-four ligands are presented. Based on the calculating results and the
electroneutrality principle, the condition for the coordinative atom and the donor atoms
in carbonyl compounds, phosphorus(Ⅲ) and arsenic(Ⅲ) complexes, as well as linkage
isomers of SCN^- and other ambidentate ligands are discussed.
